3 Operation Manual About this manual Thank you and congratulations on selecting this professional weather station! We are positive you will enjoy the benefits of accurate weather readings and the precise radio controlled time information that our instruments offer. This manual will guide you step-by-step through setting up your PCE-FWS 20 device. Use this manual to become familiar with your professional weather station, and save it for future reference. Glossary of Common Terms DCF/WWVB The DCF or WWVB time signal is an AM modulated time-of-day signal broadcasted by the Federal Government of Germany or NIST from USA. The time base is generated from an atomic time generator which is accurate to 10 billions of one second. LCD LCD is an acronym for Liquid Crystal Display. This is a common type of display screen used in televisions, computers, watches, and digital clocks. BAROMETER & BAROMETRIC PRESSURE A barometer is a device that measures the pressure of the air pushing on it this measurement is called the barometric pressure. We don t actually feel the barometric pressure because the air pressure is pushing equally in every direction. RELATIVE AIR PRESSURE Relative air pressure is the same as the barometric pressure. The calculation of relative air pressure is a combination of the absolute air pressure and the altitude. ABSOLUTE AIR PRESSURE Absolute air pressure is the actual air pressure on the barometer without regard to altitude. INCHES OF MERCURY (inhg) Inches of Mercury is the common unit of measurement for air pressure in the United States. HECTOPASCALS (hpa) Hectopascals are the common units of measurement for air pressure in the International System (SI) of measurement. The hectopascal holds the same value Important Note: Before inserting batteries, please carefully read the operation manual. The touch screen weather station PCE-FWS 20 includes a base station (receiver), a transmitter unit, one wind direction sensor, one wind speed sensor, one rain gauge, USB cable and a PC software package on CD-ROM. 3

4 The Base Station is equipped with a Touch Screen LCD Monitor and allows the display of a large variety of time and weather data. Left Top LCD: IN-OUT temperature and humidity Right Top LCD: Wind and Rain measurement Left Middle LCD: Weather Forecast (Tendency) Right Middle LCD: Air Pressure and Air Pressure History Bottom Line LCD: Time and Date, Memory Data Usage Note: The presence of the "Alarm-On icon" in the section means that the particular alarm has been enabled. An added feature of the Weather Station is the readout of all measured and displayed time and weather data on a PC as well as the ability to upload the data to Internet Web Sites. Important Operation Notes All actions and functions of the weather station are started on the touch screen by slightly Touching (not pressing!) the related areas, touch the flashing +, ON/OFF or to make the corresponding selection or increase the value. Every time a programming step is activated by touching a switching area on the Touch Screen a tone will sound, and the back light is switched on for a few seconds as well. If no areas are pressed for 30 seconds, the LCD will automatically revert to the normal display mode (automatic time out). Getting Started 4

7 Important Notes: On the edge of wind direction sensor, there are four alphabet letter of N, E, S and W representing for the direction of North, East, South and West. Wind direction sensor has to be adjusted so that the directions on the sensor are matching with your real location. Permanent wind direction error will be introduced when the wind direction sensor is not positioned correctly during installation. Wind speed sensor wire has to be inserted into the phone jacket on wind direction sensor. Wind direction sensor wire has to be inserted into the phone jacket located on the thermohygro sensor with marking of Wind on top. The rain sensor wire has to be inserted into the phone jacket located on the thermo-hygro sensor with marking of Rain on top. System Start Insert two pieces of LR6 (AA size) batteries into the transmitter, the LED located in the middle front case of transmitter will be turned on for 4 seconds and then it will be off and start to work normally. The transmitter will make a data transmission and then start radio controlled time reception routine. If time signal can be detected correctly, then the LED will start to flash 5 times indicating time signal has been found correctly. When time signal is bad and reception is not possible, the transmitter will terminate radio controlled time reception within one minute and resume normal mode. When there is a data transmission happened, the LED will be on for 20ms. During radio controlled time reception period, there is no transmission and normal transmission will only resume after time reception routine is complete. The longest time for radio controlled time reception is 5 minutes. After inserting the batteries into the Weather Station, all LCD segments will be turned on for a few seconds, all possible display segments are turned on for checking. After this, the weather station will make initial measurement and start to register the transmitter ( the radio reception icon will be turned on). Before there is outdoor data received, it is not allowed to touch the LCD, otherwise the outdoor sensor learning mode will be terminated right after the touch of LCD. When outdoor transmitter has been registered, the Touch Screen Weather Station will automatically switch to the normal display mode from which all further settings can be performed by the user. 7

8 If no RCC signal is detected in the initial setup, the transmitter will try once every hour to get an RCC signal until a signal is received. Once the transmitter receives the RCC signal it will transmit the signal to the monitor. On the monitor the RCC icon will be displayed, if the monitor doesn t receive the RCC signal or loses the signal the RCC icon will not be display. Note: The best condition for reception is at night, between midnight and 6:00am when there is less atmospheric interference. Positioning Once you have verified that all of the components of the weather station are working, they can be positioned in their permanent places. Before permanently mounting, make sure that all components work properly together at their chosen mounting or standing locations. If e.g. there appear to be problems with the 868 MHz radio transmission, they can mostly be overcome by moving the mounting locations. Note: Commonly the radio communication between receiver and transmitter in the open field can reach a distance of up to 330 feet providing that there are no interfering obstacles such as buildings, trees, vehicles, high voltage lines, etc. Radio interferences such as PC screens, radios or TV sets can, in bad cases, entirely cut off radio communication. Please take this into consideration when choosing standing or mounting locations.

Press and hold the memory full icon for 3 seconds will clear the memory. PC Connection As an important feature in addition to the display on the Touch Screen, the Weather Station allows the read-out of all measured and displayed time and weather data in form of complete history data sets on a PC. Data Storage For a comprehensive weather history, the Base Station allows the internal storage of up to 4080 complete sets of weather data with time and date. These data sets are being stored in non-volatile ring buffer memory (EEPROM) and will not be lost even in case of an interruption of power supply (e. g. change of batteries). In case the memory capacity of the Weather Station is exhausted the oldest data sets stored will be overwritten by the new ones entered. Data Recall Certain weather data or setting values can only be read out, processed, and displayed by means of a PC. Also the settings of the storing intervals from 5 minutes to 250 minutes for the storage of data sets can only be performed by means of a PC. Connections and Software The wiring between Weather Station and PC takes place by means of an included USB cable. The Easy Weather software package, also included in the shipping contents, must be installed on the PC. This software allows the display of all present weather data with graphic symbols. It also allows the display, storage, and printing of history data sets, whose volume exceeding the maximum 4080 data sets of the Weather Station is only limited by the capacity of the PC s main memory. PC software installation The installation of PCE-FWS 20 software is very simple: double click the setup.exe file and follow the steps popped up. Make sure you are running the program under the administrator accounts of your windows PC platform. 16

17 Otherwise the graphic function might not be working when graph display mode is needed to display all history data. If you run the program for the first time, the current weather display will be displayed and at the sub line of the window, the program will show related information regarding the read of all history data into the PC. Please note however, when there is large amount of data is being uploaded, it will take a few minutes time before the system can respond to your setup settings. Otherwise it will display read weather data fail error message since the USB port is reading the data from the memory and the system is not able to respond any further job tasks. 17

18 When memory is full, it will take about two minutes to upload all history data into PC and it takes another two minutes to process all history data for graphic display.

If successful, then the following window will be displayed: 28

29 Special Notes about time synchronization between PC and sub-station: The PC software obtained its own time scale through the time interval marker from the base station history data, and the PC software automatically synchronizes the weather data with a time stamp calculated. Thus the history data file can have different time when the PC time and base station time is not same. In order to make the time scale correct, remember to set the PC time and base station time same, and further to this, no weather data is allowed to be missed or over-written. If history weather memory on the base station is cleared by manual setting, then the history weather data since last uploading is lost permanently. Before memory is used up(memory icon on LCD display showing 100% full), remember to upload weather history data to PC periodically. If there is a reset happened for the rain fall on the base station, then there will be rain fall value discrepancy between PC and base station.
